What is leprosy epidemiology?

Leprosy is a chronic infectious disease caused by the bacillus Mycobacterium leprae. While the organism is readily transmitted from person to person, it does not usually produce the clinical disease because of intrinsic human resistance to the infectious agent in the majority of people.

Is leprosy endemic or epidemic?

Leprosy is caused by Mycobacterium leprae and has been known since biblical times. It is still endemic in many regions of the world and a public health problem in Brazil.

What are the 4 types of leprosy?

Leprosy

  • Borderline Lepromatous Leprosy.
  • Borderline Tuberculoid Leprosy.
  • Indeterminate Leprosy.
  • Lepromatous Leprosy.
  • Midborderline Leprosy.
  • Tuberculoid Leprosy.

What are the three types of leprosy?

The first system recognizes three types of Hansen’s disease: tuberculoid, lepromatous, and borderline. A person’s immune response to the disease determines which of these types of Hansen’s disease they have: In tuberculoid Hansen’s disease, the immune response is good.

What is the pathology of leprosy?

Leprosy is a chronic infection caused by the acid-fast, rod-shaped bacillus Mycobacterium leprae. Leprosy can be considered 2 connected diseases that primarily affect superficial tissues, especially the skin and peripheral nerves. Initially, a mycobacterial infection causes a wide array of cellular immune responses.

Which bacteria causes leprosy?

Hansen’s disease (also known as leprosy) is an infection caused by slow-growing bacteria called Mycobacterium leprae. It can affect the nerves, skin, eyes, and lining of the nose (nasal mucosa). With early diagnosis and treatment, the disease can be cured.

What are the determinants of disease in epidemiology?

In the definition of epidemiology, “determinants” generally includes the causes (including agents), risk factors (including exposure to sources), and modes of transmission, but does not include the resulting public health action.

What are epidemiological factors?

1: Epidemiologic Factors Events, characteristics, or other definable entities that have the potential to bring about a change in a health condition or other defined outcome.

What are the main causes of leprosy?

Leprosy is caused by a slow-growing type of bacteria called Mycobacterium leprae (M. leprae). Leprosy is also known as Hansen’s disease, after the scientist who discovered M.

How leprosy is diagnosed?

You may not feel a light touch or a prick with a needle. To confirm the diagnosis, your doctor will take a sample of your skin or nerve (through a skin or nerve biopsy) to look for the bacteria under the microscope and may also do tests to rule out other skin diseases.
